Title: Dynamic Sealing Shaft Texture

Presenter: Matt Novak, Bruker

Abstract

Surface characteristics play an integral role in the function of machined and moving (dynamic) systems, one specific example being the surfaces in contact in dynamic sealing systems. When problems (leakage, for example) arise in a sealing system, it is challenging to pinpoint the root cause as there are many variables to address. The system lubricant, the seal material and seal integrity, as well as the surface of the shaft that is in motion in the system all interact to create the dynamics of the sealing system.

In this presentation you will hear about accurately quantifying and reporting on surface roughness, texture and functional surface parameters, including shaft surface lead, during production of the shaft surfaces for sealing systems. The concepts discussed may be new to some since the methods for characterization discussed will be non-contact, 3D optical profilometry using a 3D optical microscope system as opposed to traditional stylus based profilometry-based metrology.
